Over the last few decades, the focus of decentralized urban stormwater management has changed significantly from what was essentially a water quantity mindset to approaches that added significant water quality improvements. The old school concept preventing local basements from flooding while conveying excess volume to downstream stakeholders had to be rethought. New solutions had to be considered.
The EPA introduced design concepts like Rain gardens and Low Impact Development that changed the game and emphasized treating the runoff as close to the source as possible. That led to further consideration of replacing large centralized treatment BMPs to smaller BMP implementation like Water Quality Inserts (WQIs), which could be retrofitted in a decentralized manner into existing inlets. Soon it became clear to designers that the same water quality and cost benefits that held for retrofit applications could also apply to new construction as the same basic inlet infrastructure is required to collect the run-off. It is more cost effective to incorporate WQIs into inlets than to incorporate stand-alone centralized downstream treatment structures.
Fabco Industries is a leader in stormwater filtration treatment products and engineering, with an emphasis on decentralized solutions. We design and manufacture high-performance stormwater filter systems that are highly effective for various treatment applications including retrofits, new construction, and green infrastructure. In responding to clients’ design needs, Fabco soon realized that while decentralized treatment can be considered as an option on almost any project, there are situations where decentralized solutions are the only practical solution. Applications such as inlets near streams or shorelines, at port facilities and on bridge decks fall into this category. Following are a few examples of where Fabco decentralized WQIs were implemented in those types of applications.
Gibson Avenue Marina
The inlet above is in close proximity to the marina in the background.
The inlet feeds a plastic perforated pipe that conveys the discharge directly into the receiving water body of the marina.
Fabco’s TSS cartridge (red ring) was selected for this application. The TSS cartridge will target both the particulate and the particulate associated pollutants to provide enhance water quality treatment.
A series of inlets in close proximity to the harbor’s receiving waterbody needed water quality treatment incorporated.
Fabco’s standard inlet survey process assured that the StormBasin Water Quality Inserts (WQIs) would fit the inlets properly.
The above application was driven by the location of the inlet relative to the shoreline. With the rise in beach closings due to bacteria levels, Fabco’s FabGuard proprietary bacteria treatment media is an effective solution. For large treatment volumes, the FabGuard is often configured into a helix filter/vault but for inlets close the shoreline FabGuard bacteria removal cartridges are a practical solution.
While the first two examples showed applications that used StormBasins with our cartridge filter systems, this project utilized our StormSack geotextile filter bag option to filter water entering the body of water shown behind the inlet.
In this application, multiple runoff collection structures at different locations come together and convey polluted runoff into a nearby receiving water body.
Our range of durable, cost-effective products is designed to meet increasingly stringent pollution control regulations and best management practices for municipal and commercial stormwater treatment. While similar examples were shown in terms of the decentralized concept, pollutant targeting is also a big part of the Fabco equation. Fabco offers WQIs that are basically trash and debris screens, geotextile and screen WQIs for TSS and filter cartridges (shown above) that can target TSS, Nutrients, Pathogens or heavy metals.
